Tubing is hard to make sooo..

 

An early notable method for producing metal tubes quickly and inexpensively was patented by James Russell in 1824. In his method, tubes were created by joining together opposite edges of a flat iron strip. The metal was first heated until it was malleable. Using a drop hammer, the edges folded together and welded. The pipe was finished by passing it through a groove and rolling mill 

 

Ah hah. Clay over a wooden mandril. 

Mohenjo-Daro, a town of 35,000 in the Indus River Valley (southern Pakistan), is considered by many historians to be the birthplace of sewers. Beginning around 3500 BCE, drains made of cut stone or man-made masonry units, initially open topped but later covered, were developed and became the prototype of many surface drains used throughout the ancient world – the forerunners of pipe. The birth of pipe occurred at about the same time in Babylon (Iraq) – sun-cured (and later baked) terra cotta pipe made on wooden mandrels, with bell and spigot joints. The idea of sewers and pipes spread far and wide over the next few thousand years
